Primary Primary cards are going to be something that you examine first. There might be certain meta’s that don’t require one of these cards, but generally speaking you will always have some number of these cards in your 15.Smash to Smithereens: the reason it’s useful in Legacy is that a lot of decks use artifacts to extend and generate additional flexibility and this generates a good two-for-one.REB / Pyroblast: extremely potent in Legacy, so much in fact that some players have chosen to play one or two maindeck in their lists just because they are relevant that often. Also, having a one-mana hard answer to push through a Fireblast or Price of Progress is super relevant.Searing Blood / Searing Blaze: the Smash to Smithereens of creatures. They offer incredible value for their cmc and should be valued above sweepers. I really do prefer a 3/2 split between Searing Blaze and Searing Blood. Fetchlands make Blaze much less conditional. This is why Blaze is seeing maindeck play while Blood is not. Blaze is still doing three damage against an opposing Tarmogoyf or Batterskull. Blaze gets around Misdirection and Protection (in response to targeting). Now the nice thing about Searing Blaze is that it doesn’t need to resolve in order to gain the burn aspect. On the other end, Searing Blood gets around Leyline of Sanctity very well as it doesn’t target a player.

Secondary are cards that should be included in most sideboards. They are relevant in over 75-percent of the meta and are the ones that have answers to more than just one deck.Pithing Needle is a card that I am starting to fall in love with more and more as Lands and Jitte pick up in value. It’s really actually very nice to have a “clean” answer to all permanent types without being a big investment mana-wise. The ability to get an answer to Top, Stage, Jitte, Stoneforge Mystic and Jace is great. The fact it can be a dead card that can be hit by Abrupt Decay or Wear // Tear is somewhat of a liability.Tormod’s Crypt, Relic of Progenitus, Leyline of the Void, Faerie Macabre, Surgical Extraction, and Grafdigger's Cage should cover all your graveyard hate. The benefit of the first two is that they are cast-able in our deck while Leyline isn’t. Faerie has the benefit of not being countered. Surgical Extraction has a lot of synergy with Burn builds that utilize Young Pyromancer. I think that if I was heading into a meta that has many Tin-Fins, Dredge, and Graveyard-centric strategies I’d be sideboarding four Leylines of the Void. I think if I was heading into a meta that has some graveyard strategies, but is primarily midrange Blue strategies, I’d be bringing Relic as it handles both graveyards (for Goyf) and replaces itself. Finally, you have Cage, which is ideal for handling graveyard strategies like Reanimator as well as Elves.Ensnaring Bridge is probably one of the most overvalued and undervalued card in our list. Three mana is a lot for us as it’s our top end of the curve and with cards like Fireblast in our list, we aren’t even promised more than two lands a game. In the games that you want to see Bridge it is very, very good. I think Bridge is one of the best answers to Goyf and Sneak and Show/Reanimator as it can turn off their win-con unless they have artifact hate in the deck and most won’t. It also provides answers to elves (although they have Abrupt Decay), Delver, Junk, Stoneblade, and Zoo. I really do think that people should be testing Bridge more in more defined metas.Vexing Shusher has been in the last four decks to Top-16 an SCG Open. It is a “red hate bear” (along with Eidolon of the Great Revel) that can’t be countered. In a meta full of counter-top it is very strong. It also generates a nice advantage against midrange Blue decks as well. Be careful though as it can be a bad mana sink for our decks as it can bottleneck our limited mana availability.Chaos Warp is very unique from a card development standpoint as it is the one of the few cards that is a straight up hard answer to permanents in Red. What is nice is that it’s a pretty clean answer to Leyline, although there is always a chance we Chaos Warp away a Leyline into a fresh, new Leyline. Boo.Satyr Firedancer doesn’t see enough play for the effect it provides. Sure it has a small body, but it provides an answer to the age-old question of “Bolt the Delver or Bolt the Face?" I prefer to bring it in against Delver, Elves, Maverick, and other decks that require some creature interaction because even going Bolt+Bolt against a Primetime is good with this guy out.Ratchet Bomb can be another great utility spell as it answers problematic creature-hate (stupid Firewalkers), problematic artifacts (Jitte, Batterskull), enchantments (looking at you Leyline and Sneak Attack) and other stuff that we might not be prepared for. Pyrostatic Pillar is a very good magic card. It was so good of an enchantment that Wizards felt fit enough to make it into a creature in Eidolon of the Great Revel. It is very good against Storm and is good enough against some delver variants to offer consideration based off the match at hand. Also fairly good against Elves. Meta Meta sideboard cards are cards that are extremely powerful, but overall very, very narrow. These are cards that can completely destroy a strategy, but require heavy investment because they are useless outside of the matches that they are great it.Anarchy is one of our answers to Leyline and what is nice is that it gets around shroud/hexproof protection as well. It is four cmc though, which is pretty much infinite mana in Burn so keep that in mind.Mindbreak Trap is probably one of the strongest cards we have against Storm as when it is cast properly it just stops them dead. I honestly think that the two damage per spell that Eidolon offers is better, because it gets us that much closer to our goal of 20 points of damage, however, I can see the appeal of Trap. Also, it does have uses outside of Storm. For example I was playing against a Burn deck and was up a game. We both had Eidolon in play and essentially I thought I bottlenecked him in a way that his only answer was to take damage from Eidolon if he wanted to kill me that turn and that damage put him into Fireblast range. Turns out, he had a Mindbreak Trap and destroyed me. It was a tough loss and to this day I probably still would never play around Trap in a mirror match but it’s always possible.Volcanic Fallout is a unique card. I do not think we should ever be playing Flamebreak in our deck as it just isn’t a good source of advantage for its high cmc. The reason I think this isn’t true about Fallout is that it is uncounterable. There will be many games you lose because you could only do 18/19 points of damage. Having an opponent win or stabilize at one life can cause even the most level-headed Red mage to tilt. Why fallout over sudden shock? Because I really do think that it is a huge resource advantage to board this in against Canadian Threshold/RUG Delver decks, because it takes out two of their three threats while allowing damage to get through.
